Title (EN) PIXEL CIRCUITRY FOR ULTRA WIDE DYNAMIC RANGE
(FR) CIRCUITS DE PIXELS POUR PLAGE DYNAMIQUE ULTRA LARGE
Abstract: front page image
(EN)The pixel circuitry of the invention enables light sensing through a photo-current mode with logarithmic compression and through accumulation of charges, with a seamless transition between the modes that depends only on the light signal strength, and not on external control signals. The pixel circuitry of the invention also allows said photo-current mode for a pixel matrix operated in the electronic global shutter mode, provides anti-blooming capability, and allows for sharing of certain pixel circuit elements between a plurality of pixels.
(FR)Les circuits de pixels de l'invention permettent de capter la lumière par mode photocourant avec compression logarithmique et par accumulation de charges, avec une transition sans à-coups entre les modes qui ne dépend que de la force de signaux lumineux, et non pas de signaux de commande externes. Les circuits de pixels de l'invention permettent aussi d'utiliser ce mode photocourant pour une matrice de pixels mise en oeuvre dans le mode obturateur global électronique, offrant une capacité anti-éblouissement et permettent aussi à une pluralité de pixels de partager certains éléments de circuit de pixels.
